Error In Uploading File - Docx Download

Team
can anyone check and help to resolve this issue.
I am trying to upload a video file after converting into the zip. The file extension is WinZip File (.zip) only.
But following error getting.
Attaching the snapshot of error getting while trying to upload.

Hi Dilip,
I am unsure why - I'll check it out. The attachment needs to be under 10MB - but I think you mentioned that it was in your private message.
The best way to include a video is probably by using the [youtube] bbcode.
Here's an example:

I placed the video id inside the [ youtube ] [ /youtube ] bbcode. The video id is taken from the URL of the youtube video.
In this case https://www.youtube.com/watch?v=kLksshFZta4
See this: ?v=kLksshFZta4
The part after the equal to sign is the video id.
So I did this [ youtube ]kLksshFZta4[ /youtube ] (you need to remove the extra spaces inside the brackets [ ] )
